Abstract

PURPOSE:To prevent the occurrence of a breakdown trouble before it happens, by a method wherein an elongation difference, twist, and vibration of a coupling are detected directly, and the valve, a first regulation of a coupling are detected directly, and the value, a first regulation value, and a second regulation value, having a higher abnormality than that of the first regulation value, are compared with each other. CONSTITUTION:A flexible coupling consists of a rotary shaft 10, diaphragms 11 and 12, and coupling 13 and 14. A monitoring device is provided with elongation difference detectors 15 and 16, twist detectors 17 and 18, and vibration detectors 19-22 to always and directly detect the elongation difference, twist, and vibration of the diaphragms 11 and 12. A first and a second regulation value of the elongation difference, twist, and the vibration are stored in a comparator 67 beforehand. The first regulation values DELTAl, DELTAtheta, DELTAlambda are set to a safe allowable value which is to extent that the part of the flexible coupling is safe allowable value which is to extent that the weakest part of the f lexible coupling is not broken, and the second regulation value DELTAl', DELTAtheta', DELTAlambda' are set to a value whose abnormality is higher than that of the first regulation value. The comparator 67 sends a command to an alarm circuit 68 when one of the detection values attains the first regulation value, and transmits it to a controller 69 when the detection value further reaches the second regulation value.
